Paul Scheuring directs this gripping thriller about a group of ordinary men who volunteer to take on the roles of guards and inmates in a mock prison as part of a controversial psychological experiment. When Barris (Forest Whitaker) and the other guards abuse their power in unnerving ways, Travis (Adrien Brody) and his fellow prisoners stage a revolt. Maggie Grace co-stars in this film based on the infamous real-life 1971 Stanford prison stunt.
